QUIZ GAME is a C++ program made using various user defined classes , outline functions & data file handling system.It is a user friendly program in which one can play the quiz game. Some predefined objective type questions are present. On selecting the correct option score is increased. Questions belong to four subjects : ”HISTORY/COMPUTER/SCIENCE/GENERAL KNOWLEDE”.
Class lines controls all the functions related to making lines & boxes etc. Class menu controls the menu related functions. It contains functions to create the opening screen and edit menu. Class quiz controls all the functions related to quiz. It contains functions to add, delete or modify questions,
6
in a record and to display the record for the given question no. from the given file. It also creates function to create screen for playing quiz for the player and also keeps the scores. Finally it contains the function to display the player’s score.
